Segments

A segment is a saved rule over your audience, not a fixed list: “everyone tagged trial who has not opened a campaign”. It stays current as contacts change. Any segment can be the audience of a campaign.

Open Email → Audience → Segments and choose New segment.

Build a rule

Give the segment a name (for example “VIP openers”) and add conditions. Choose whether a contact must match all of them or any of them. Contacts are included automatically when they match.

Field	What you can ask
Tag	Has, or doesn’t have, a tag.
Email domain	Is, or is not, a domain such as acme.com.
First name	Is set, or is not set.
Signed up	In the last N days, or more than N days ago.
Custom field	A field equals or contains a value.
Engagement	Opened any campaign, clicked any campaign, or never opened.
Status	Is subscribed, pending, unsubscribed, cleaned or lead.

A live count under the rule shows how many people it catches as you build (“Calculating…” while it updates), so you can see the size before you commit. Press Save segment.

Use a segment

On the send screen, choose By segment and pick it. See Build a campaign.

Good to know

• The preview is forgiving; sending is strict. A rule that is only half built can still show a count, but Svay refuses to send with a broken rule instead of widening your audience.
• Unsubscribed and Cleaned contacts are never mailed, whatever the rule says.
• Edit or delete a segment from its row. Deleting one does not delete the contacts in it, but campaigns that target it will need a new audience.
